T 0 all 10 710m it may 0071 6'67")1 Be it known that I, EMLEN A. FRANKLIN, a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented new and higher specific gravity will pass therethrough, while lighter particles, such as grass and weeds, will be screened out.

My invention further comprises means, preferably adjustable, located in the traje'ctory of the particles that pass through the screen, so located that a separation will be effected between the. particles of differing specific gravities.

My invention further comprises a series of fluid screens, interposed successively across the trajectory of the particles so that foreign matter, of lower specific gravity will be screened. out progressively, that is to say the nrst screen will takeout the lighter particles, the next screen will take out the next heavier particles, and so on.

My invention further comprises means to regulate the density, that is to say, the screening out ability, of the several fluid screens,

My invention further comprises an 1mproved form of casing fora separator in which tailings are projected horizontally, the contour of the casing being such that the projected particles, which leave the projectingmeans at a tangent follow around on the inside of the casing, pass through the series of fluid screens and then fall into further separating means positioned at the other end of the casing.

In the drawings, which are diagrammatlc,

Figure 1 1s a plan view of my improved tailings separator;

Fig. 2 is a side view, partly in section, taken onthe line 2-2 of Fig. 1 r

Fig. 3 is a sectional view, in elevation, of the separator casing and cooperating parts;

4 is a view similar to Fig, 3, of a modification; and i Fig. 5. is an enlarged view of one of the flu1d screen forming elements. i

Referring now to the drawings in which similar reference characters indicate similar parts, 1 indicates the separator casing which is curved as shown and which has positioned therein, toward one end, a projecting means for throwing the tailings across to the other side of the casing in a substantially horizontal path. This projecting means ishere shown as a wheel mounted on. the'shaft 2, and provided witharms or blades 3, preferably slightly curved. The shaft 2 is mounted in bearings 4 and 5.

The shaft 2 has mounted thereon a pulley .6 around'which engages a beltT, the'belt 7 in turn being driven by a pulley 8 mounted on shaft 9, said shaft 9 carrying a pulley 10 which is rotated by a belt 11 driven by a variable speed motor 12. I t

The beet sugar tailin s, containingweeds, grass and stones are 7 ed into achute 13' from the pickings table. These tailings drop into a hopper 14 and are then carried upwardly by the belt conveyer 15 of any desired design and dumped into a feed chute 16 that feeds the tailings into the arms 3 of the projecting wheel, designated 3'. Y j I I 'The belt conveyer 15 may be driven from a shaft 17 provided with a sprocket 18, which in turn is driven by the. chain 19 ,enaging with the, sprocket 20 on shaft 21. haft-f ll is driven by a gear 22 meshing with a gear 23 mounted on shaft 5. The conveyer belt 15 turns on suitable drums 24 and 25, the lower one 25 of which may be adjustable by the threaded shaft 26 engaging with the bearing 27 of the shaft 28, that carries the drum 25.

fluid is ,fed to these spray pipes 29' through a series of-pipes 30, each controlled by a valve 31, whereby it will be apparent that the density of each individual fluid screen may be regulatedat will.

These spray pipes 29 are shown in more detail in Fig. 5 and while they may be made.

in several possible forms are here shown as a pipe provided with a series of holes 29 drilled in the bottom thereof so as to form a downwardly directed spray.

This downwardly directed spray when interposed across the path of horizontally projected tailings is particularly efficient in removing foreign matter of lighter specific gravity, because the action of gravity aids the screening out of these lighter particles. The plurality of fluid screens the density of each of which is readily adjustable gives an apparatus which has a wide range of use, in that it may be regulated to handle tailings containing particles of widely varying specific gravity.

The wheel 3 is rotated in the direction of the arrow to throw the tailings in a substantially horizontal path into. the fluid screens.

The casing 1 is curved as at 32 toguide the 7 particles as they leave the projection wheel 3 into the fluid screen. On the other side of the fluid screen the casing 1 is clownwardly curved, as at 33, to guide particles that have passed through the screen into suitable receiving means located at the right hand side of the casing.

This receiving means comprises essentially a horizontally adjustable partition 34, carried by a frame 35 extending exteriorly of the casing. This partition is adjustable be tween the positions shown at 34 and 34. The partition 34 has pivoted thereto a cooperating partition 35, the pivot being indicated at 36. Partition 35, at its lower end is curved, as shown at 37 to engage over a rod 38, so as to permit movement when the artition 34 is moved to the right or left. artition 35 is provided with a guide plate 39. I The partitions 34 and 35 cooperate with partition 40 to define between them a trash receiving space 41, into which space 41 particles of lesser specific gravities are carried by the screening out action of the several fluid screens. These lighter particles fall into abin defined by the racks 42 and 43' and are conveyed away by any suitable means.

The particles that pass through the fluid screens have a greater or less trajectory depending on whether or not they have a high or low specific gravity. A separation of these particles according to their specific gravity is obviously effected by adjustment of the partitions 34 and 35.

The particles that fall to the right of the partition 34, when beet sugar tailings are being separated, commonly contain, in addition to beet particles, such undesirable foreign matter of higher specific gravity, such as stones, nails, and so on. This mixture falls into a flotation process separating box 44, of any conventional design provided with the usual perforated bottom plate 45.

and a feed water pipe 46. The lighter particles are floated ofl by this: flotation process and pass down the feed chute 47 The bottom of the box may be hinged to dump out the stones and metallic particles from time to time.

The function of the plate 39 is to guide particles that have fallen to the right of the partition 34 into the flotation box 44. The operation of the device is no-wthought obvious. The use of a variable speed motor enables my separator to be used not only for. beet sugar tailings but for separating uses in general, for by varying the speed of'the motor particles of different specific gravities are readily separated. The series of fluid screens each individually adjustable, and each downwardly directed, and which may be formed by air, wateror other fluid, enables my separator to be used to separate tailings which may contain particles that are relatively high or relatively low in spercific gravities.

Referring no.w to the modification shown in Fig. 4, a somewhat different receiving means for the screened out particles and for the particles that pass through the fluid screen, are shown. A partition 48 is vertically adjustable, so that the particles of higher specific gravity will pass over it while those of lighter specific gravity will fall to the left of it into the bin 41. A plate 49 pivoted at 50 cooperates with the plate 48 to guide the particles into the space 41. By positioning the plate 49 in the position shown in dotted lines at 49, an additional separation may be had, the particles so separated out, called middlings, passing out into the chute 51. Otherwise this modification comprises the projecting wheel 3', the fluid screen forming pipes 29, flotation box 44 and cooperating parts. While I have illustrated possible embodiments of my invention, it should be understood that it may be carried out in other ways as defined in I the following claims.
